What is the constant of proportionality, \dfrac{y}{x}
x
y
​
start fraction, y, divided by, x, end fraction ?

Answer 1

Answer:

k = 3.5

Step-by-step explanation:

The equation representing a proportional relationship is

y = kx ← k is the constant of proportion

Divide both sides by x , then

k = $\frac{y}{x}$

Using the point (1, 3.5 ), then

k = $\frac{3.5}{1}$ = 3.5
